Opis:
EU Biodiversity Strategy for 2030 aims to restore 25,000 km of free-flowing rivers across Europe. The critical issue is which barriers should be prioritised for removal. In this study, a set of socio-economic and environmental criteria was chosen to rank the dams on salmonid rivers in Lithuania and recommend them for removal. As these criteria usually contradict themselves, the multi-criteria decision analysis tool was utilised. The results showed that the Anykščiai dam on the river Šventoji could be recommended to be removed first. The removal can significantly increase the salmonid population in the river Šventoji over a significant stretch of the river. Also, this dam is in a protected area, is not listed as a national heritage, and does not have a hydropower plant. Although, this study showed that dams with hydropower plants could also be recommended for removal.

Opis:
The research results presented in this article are an answer to the controversial theses questioning the validity of traditional recycling methods. The voices of scientific circles which have appeared recently indicate that irrational waste management and energy-intensive recycling of selected products bring more harm than benefits to the environment. This paper is devoted to the assessment of selected environmental effects of traditional recycling processes for container glass. The environmental impact of collection, segregation, transport and remelting of glass waste was analysed using the LCA (Life Cycle Assessment) method and available databases. The environmental impact of the processes described was assessed in terms of selected criteria: climate change, energy depletion, air emissions, toxicity and depletion of natural resources. Two methods were used for the calculations: the method of the Institute of Environmental Engineering of Leiden University–CML and the Ecological Scarcity Method (ESM). The calculations were carried out for an exemplary city located in eastern Poland. The study showed that, compared with purely natural glass production, the production of recyclates was more favourable in terms of all the above-mentioned factors. Additional calculations made it possible to estimate the waste transport distance, for which the environmental impact of transporting recyclate to the glassworks made the glass recycling process by re-melting less favourable than the production of packaging from natural resources.

Opis:
The need to reflect upon the environment and the creation of a concept of environmental philosophy resonated in the philosophical thinking of the 1980s and 1990s. It seems that the advent of national and international institutions, which were “given” the responsibility for environmental issues, the importance of creating environmental principles, and pursuing environmental goals, has seemingly dwindled. The relationship with the environment has turned into the relationship of a citizen to his or her country, and with the principles and standards taking the form of legal regulations, the issue quickly became a matter of abiding by the law. Whilst discussion on how the normative criteria are set continued, its focus shifted to the questions of how and why they should be gradually made stricter, factoring in the economic interests of enterprises, and the time needed for setting up the processes, and developing new technologies. Environmental philosophy gradually integrated into bioethics in a broader context. This paper discusses the question of whether the integration of the environmental philosophy of bioethics helped to better promote the idea of environmental responsibility and environmental ethics, or otherwise. The study aims to initiate a discussion on whether this was a step in the right direction, and to assess how effective it was in relation to the pursuit and formation of environmental criteria.
Potrzeba refleksji nad środowiskiem i stworzenie koncepcji filozofii środowiskowej odbiła się echem w myśleniu filozoficznym lat 80. i 90. XX wieku. Wraz z pojawieniem się instytucji krajowych i międzynarodowych, które “obarczono” odpowiedzialnością za kwestie środowiskowe, znaczenie tworzenia zasad ochrony środowiska i dążenia do celów środowiskowych pozornie zmalało. Relacja ze środowiskiem przekształciła się w relację obywatela do swojego państwa, a wraz z zasadami i normami w postaci regulacji prawnych kwestia ta stała się kwestią przestrzegania prawa. W toku dyskusji nad ustalaniem kryteriów normatywnych skupiono się na pytaniach, jak i dlaczego należy je stopniowo zaostrzać, uwzględniając interes ekonomiczny przedsiębiorstw oraz czas potrzebny na uruchomienie procesów i opracowanie nowych technologii. Filozofia środowiskowa stopniowo integrowała się z bioetyką w szerszym kontekście. W artykule odniesiono się do pytania: czy integracja środowiskowej filozofii i bioetyki pomogła w lepszym promowaniu idei odpowiedzialności środowiskowej i etyki środowiskowej, czy też nie. Opracowanie to ma na celu zainicjowanie dyskusji na temat tego, czy był to krok w dobrym kierunku oraz ocenę jego skuteczności w realizacji i kształtowaniu kryteriów środowiskowych.

Opis:
The European Green Deal is a comprehensive initiative aimed at reshaping the functioning of the European Union towards sustainable development. While the immediate trigger for this initiative of the newly appointed European Commission under Ursula van Leyen was the need to address the challenges associated with climate change and to move towards carbon-free and circular economy – its goals seem to be much more ambitious: to put into practice the concept of sustainable development. Against the background of the concept of sustainability and its various ambiguities and interpretations, the article provides a brief description and analysis of the key pillars of the Green Deal, namely: the financial framework for promoting sustainability, the climate and energy strategy, and the strategy for industry and circular economy. It also presents and critically assesses the horizontal goals of the Green Deal i.e. improving involvement of the public into the decision-making and assuring equal opportunities for marginalised groups.
Europejski Zielony Ład jest kompleksową inicjatywą mającą na celu przekształcenie funkcjonowania Unii Europejskiej w kierunku zrównoważonego rozwoju. Podczas gdy bezpośrednim powodem dla tej inicjatywy nowo wyznaczonej Komisji Europejskiej pod przewodnictwem Ursuli van Leyen była potrzeba rozwiązania wyzwań związanych z zmianami klimatycznymi oraz zapoczątkowania tworzenia niskoemisyjnej gospodarki o obiegu zamkniętym - jego cele wydają się być znacznie bardziej ambitne: realizacja w praktyce koncepcji zrównoważonego rozwoju. Na tle koncepcji zrównoważonego rozwoju i różnych sposobów jej rozumienia i interpretacji, artykuł zawiera krótki opis i analizę kluczowych filarów Zielonego Ładu, a mianowicie: ram finansowych promowania zrównoważonego rozwoju, strategii klimatycznej i energetycznej oraz strategii dla przemysłu i branży i gospodarki o obiegu zamkniętym. Prezentuje również i krytycznie ocenia horyzontalne cele Zielonego Ładu, mające na celu poprawę zaangażowania społeczeństwa w podejmowanie  decyzji i zapewnienie równych szans dla grup marginalizowanych.

Opis:
The research was devoted to studying the influence of the Tamir biological product in the loose deep-litter keeping of the cattle on the indicators of rearing stock live weight, average daily weight gain, and withdrawal of replacement heifers, cows, and first-calf heifers due to the limb diseases. The study was performed at the stud farm for breeding the black-motley breed of the Integrated Agricultural Production Company (collective farm) Udmurtia in the Vavozhsky district of the Udmurtian Republic in the period from 2013 to October 2018. The report on animals culling from the main herd, and reports on animals weighing have shown that in 2013–2014, before the use of the biological product, the number of heifers withdrawn from the herd at the age of 10–12 months was 12 (in 2013), or 1.4%, and 13 (in 2014), or 1.4%; at the age from 12 to 18 months – nine (2013), or 1.1%, and 12 (2014), or 1.3%; at the age of 18 months and older – three (2013), or 0.6%, and eight (2014), or 0.5% of the total number in the age groups of the animals. In 2015–2017, i.e., after the use of the biological product, the number of heifers withdrawn from the herd at the age of 10–12 months was nine (1.1%), six (0.6%), and seven (0.6%); at the age of 12–18 months – seven (0.8%), five (0.5%), and three (0.3%); at age 18 months and older – two (0.2%), two (0.2%), and one (0.01%) of the total number in the age groups of the animals. Withdrawal of rearing stock due to limbs diseases was also analyzed. While before the use of the biological product, in 2013–2014, 26 animals, or 3.0% (2013) and 33 animals, or 3.5% (in 2014) had been withdrawn from the herd, after the use of the biological products in 2015–2017, this figure dropped to 18 animals, or 2.2% in 2015, 13 animals, or 1.2% in 2016, and 11 animals, or 1.0% in 2017. Thus, the percentage of the withdrawn heifers after the use of the biological product decreased from 3.0–3.5% to 1.0–2.2%, or almost three times. Analysis of the average daily weight gain by young animals in all age periods has shown that after the use of the biological product, the average daily weight gain increased, compared to the period before its use, which confirms the growth of this indicator. The live weight of the replacement heifers at first insemination before the use of the product amounted to 382–381 kg, and in 2015–2017, after the use of the product, it amounted to 385–388–390 kg, which also indicated the positive effect of the product on the growth. The percentage of the cows withdrawn from the main herd after the use of the biological product reduced from 10.3–15.4% to 5.8–6.1%, i.e., by 4.5–9.3%; of first-calf heifers – from 11.0–17.1% to 3.4–7.1%, i.e., by 7.6–10.0%, by the years of withdrawal, respectively. After processing the manure with the Tamir biological product, the fraction of manure became solid (crumbly) and lost the smell. Thus, the use of the Tamir biological product in the technology of loose keeping of cattle on deep litter increased the daily weight gain in heifers and their live weight at first insemination, and reduced the share of low-productive cows and first-calf heifers, as well as the incidence rate of limb diseases.

Opis:
Assurance of the supervised conditions in all processes affects directly both products and users safety and environmental influence. ISO 9001 and ISO 14001 standards in Operation point require from organisations to implement and control the planned processes by establishing processes’ criteria, assuring the supervised conditions and verifying processes’ conformity. Moreover, in Planning section it is required to plan the processes with the consideration of quality and environmental risk. Therefore research on the practical solutions of operational planning and control in the production processes are of the crucial meaning, especially from the perspective of the integrated fulfilment of the requirements. That is why the value of the paper is being constituted by the authorial methodology of identification of the key-operational criteria, including integrated risk assessment, using the computer support and being a starting point for assurance of the supervised conditions in the key-processes of high risk. The worked out methodology has been implemented in the processes of performance and completing the stirrups, which quality is of the huge influence on the work safety of the mine roadway supports in the mine workings. The aim of the analysis was to identify the operational parameters in the stirrups technological process, to estimate their meaning and to point at the key operational criteria from the point of fulfilling the quality and environmental requirements. Practical implication of the proposed methodology can be applied in case of any organisation which wants to improve the realised processes ensuring the computer supported supervised conditions.

Opis:
It is not easy to choose a car depending on the type of engine used in it. This is due to the diversity of properties characterising certain types of cars and doubts concerning the costs incurred during their operation (especially for new types as electric cars). Thus, this article presents a comparative analysis of cars provided with different energy sources. The analysis will allow finding the answer, which of the analysed car types best meet expectations, since both electric motor-driven vehicles and combustion engine-driven vehicles have a number of disadvantages and advantages. All compared vehicles are of the same model of a single make, with different drive sources and drive systems, classified in the same market segment. Therefore, the purpose of the article is to demonstrate, which vehicle type (that is, a car with spark-ignition engine, compression-ignition engine, electric motor, or Plug-In type hybrid drive) is currently the most optimal regarding technology, economy, and environment. For this purpose, the MAJA multi-criteria assessment method which has never before been used in comparisons of this sort was chosen.

Opis:
The building objects show a wide variety. Among them, we can distinguish buildings and various building constructions. In addition to the fact that they are of various sizes, they perform different functions, while their purpose and use generates various problems, they can be made using various materials, different technologies and construction solutions. Therefore, the decision on which solutions to apply may be difficult to make. In this situation, it is good to develop several alternative solutions for their comprehensive comparison. In addition, the existing regulations that originate in the EU directives, in many cases impose the obligation to develop several variants of future investments and analyze them taking into account many factors. In the EU recommendations, the analysis related to the impact of construction investments on the environment is of highest importance. The ISO 14040–1404X regulations created and introduced by the European Union are the most important tool for a global assessment of the environmental impact of a product, facility and service. They relate to the environmental impact assessment of the entire Life Cycle Assessment (LCA), and their assumption is to identify and minimize any environmental impacts that may arise from the production, use and disposal of the product. Research should include specific stages according to the LCA evaluation system: determination of the purpose and scope of the assessment, inventory of input and output data and the impact assessment. The following research methods were used: source materials analysis, library query, advanced data collection methods through online surveys, LCA assessment, multicriterial methods. The research conducted by the author showed that the analysis involving selected problems related to the object-environment interaction is dominant. However, in practice it is difficult to find the analyses covering the entire lifecycle of an object in accordance with the LCA procedure and examples of comparison of specific design solutions within the variant assessment procedure taking into account the LCA procedure. The aim of the article is to show how such procedure can look while comparing the exemplary variants of a construction project. The article presents an example and diagrams of conduct covering the whole life cycle of an object, and the analysis is based on specific examples.

Analogies between the life cycle assessment (LCA) and multicriteria decision analysis (MCDA) methodologies have been discussed as well as LCA as an MCDA problem for resolving the trade-offs between multiple environmental objectives. The objective of this study is to compare a variety of specialised multicriteria methods and knowledge-based methods used to aggregate the results from LCA. The studies were conducted using examples of LCA on private passenger vehicles. The research used two classical methods for multicriteria decision making (AHP and TOPSIS), the method of conventional (crisp) reasoning and Mamdani’s method of fuzzy inference. The results demonstrate that among the methods analysed, only crisp reasoning does not provide satisfactory results.

Opis:
Building investment projects, both during the construction work and afterwards, have a certain impact on the natural environment when a raised structure is used. Depending on the character, size and location of a planned structure, such influences will vary. At the stage of planning a new development, investors are obliged to execute several procedures connected with the preservation of nature, for example they prepare several variants of the planned investment and evaluate which one will have the weakest effect on the environment. Assessment of variants is based on a series of criteria, and the final outcome is not always unambiguous. Hence, when trying to establish the importance of each criterion, it is advisable to apply efficient decision support methods. One option is to use multi-criteria analytical methods. However, for such methods to be applicable, an investor must prepare a wealth of information. The first stage preceding the actual analysis of variants is to define the assessment criteria and assign to them appropriate weights (importance). This stage requires the participation of experts, who – through questionnaires and interviews – express their opinions on the criteria that must be included and on their importance. This article contains a model procedure implemented for the sake of determination of the importance of parameters, which includes the methodology used for assessment and ranking of parameters. The approach presented in this paper demonstrates the usefulness of multi-criteria analytical methods when making an evaluation pertaining to the impact of a building investment on the environment.

Opis:
Sustained casing pressure (SCP) represents a major issue because of its large scale occurrence and risks to health, safety, and the environment. Present regulatory assessment of sustained casing pressure is mostly qualitative with implicit risk formulation. It currently holds that wells with casing head pressure that can be bled-down to zero and is followed by slow 24-hour pressure buildup are below acceptable level of risk. This study introduces new quantitative metrics of well integrity loss risk - the instant cement sheath leak rate of 15 scf/min (barrier integrity), and the total annual environmental gas discharge of 6 tons of volatile organic compounds (VOC) per year. Field data from 19 wells reportedly affected by sustained casing pressure (SCP) are examined with a SCP testing software to assess whether or not wells with pressure that is able to bleed to zero would meet the proposed criteria. Using modeling and software tools developed by Xu and Wojtanowicz (2001) and Kinik and Wojtanowicz (2011), it is determined that three of the 19 wells (15.8) examined would fail the instant leak rate criterion. On the total discharge criterion, assuming the wells' annuli above the cement top filled out with seawater, it was also found, again, that 15.8 percent of the wells would fail the total environmental discharge criterion. Moreover, for the worst-case scenario of absolute open gas flow (empty annulus above the cement top), five of 19 wells (26.3) would fail the criterion. It is shown that - statistically, the bleed-down of casing pressure to zero gives a 90-percent confidence of the well passing the proposed criteria. Furthermore, no clear correlation was observed between pressure build-up and the barrier integrity or the environmental gas discharge criteria, thus questioning the 24-hour pressure buildup relevance as a risk indicator.
